no mutation
substitution
insertion
deletion
A frameshift mutation can occur with either _________ or __________ mutations.
Addition, division
Deletion, substitution
Addition, substitution
Addition, deletion
The bottom DNA sequence in the image has been altered by this type of mutation
substitution
insertion
deletion
translocation
Why are insertion and deletion mutations so harmful?
They change all of the codons from the mutation on down the line, which changes the amino acid sequence
They insert things that an organism doesn't need.
They often delete things that organisms need.
Insertion and deletions are not any more harmful than substitution mutations.
What are the three types of gene mutation?
Insertion, Deletion, Subsitution
Aberration, Deletion, Substitution
Inversion, Duplication, Insertion
Insertion, Duplication, Substitution
In this type of point mutation, one base pair is lost
substitution
insertion
deletion
translocation
In this type of point mutation, one extra base pair is inserted into a sequence of DNA
substitution
insertion
deletion
translocation
The bottom DNA sequence in the image has been altered by this type of mutation
substitution
insertion
deletion
translocation
when a portion of the DNA is shifted in one direction due to a deleition or insertion
frameshift

deletion
substitution
Which type of mutation involves the removal of a nucleotide from a DNA sequence?
Substitution
Insertion
Deletion
Duplication
What is the result of an insertion mutation in a DNA sequence?
A nucleotide is replaced with another
A nucleotide is added to the sequence
A nucleotide is removed from the sequence
A segment of DNA is duplicated
In a replacement mutation, what happens to the DNA sequence?
A nucleotide is added
A nucleotide is removed
A nucleotide is replaced with another
A segment of DNA is inverted
Which of the following mutations is most likely to cause a frameshift?
Substitution
Insertion
Deletion
Translocation
How does a deletion mutation affect the reading frame of a gene?
It shifts the reading frame
It duplicates the reading frame
It inverts the reading frame
It does not affect the reading frame
Which mutation type is least likely to affect the protein function?
Insertion
Deletion
Substitution
Frameshift
